BRONZlNG-IVIACHINE.

Specification of Letters Patent.

Patented Nov. '7, 1905.

To all whom it may concern:

Be it known that we, DOUGLAS GARDNER, residing at 506 Green street,Upton Park, and JOHN OLIVER NEWTON, residing at 2 Salisbury Villas,Latchett Road, South Woodford, county of Essex, England, subjects of theKing of Great Britain, have invented certain new and useful Improvementsin Bronzing-Machines, of which the following is a specification.

The object of this invention is to fit a bronzing-Inachine with twotroughs having their bottoms provided with chamois-leather, flannel, orany other suitable material, through which the bronze-powder percolatesand is taken up by the adhesive preparation on the paper, the paperpassing under the troughs and in contact with the flannel. After thepaper has passed under the troughs it is carried against another troughcovered with flannel, which acts as a duster, the surplus powderpercolating through the flannel and falling into the trough for aftercollection.

Our invention will be readily understood from the following description,aided by the accompanying drawings, which show the upper and lowertroughs and also their application to a rotary bronZing-machine.

Figure 1 is a perspective section of a single trough having a flannel orlike covered bottom for applying the powder. Fig. 2 is a perspectiveview of a trough having a flannel or like covered top for removingsurplus powder from the paper. Fig. 3 is an end elevation of two troughsfor applying the powder and showing their connection'to their carriersand the oscillating shaft. Fig. 4 is a plan of the troughs, carrier, andoscillating shaft, part of the carrier being broken away. Fig. 5 is aside view of a rotary bronzingmachine with troughs in position.

The powder-application troughs A are constructed of box shape and withtheir bottoms covered with chamois leather, flannel, or other suitablematerial B, this being preferably held to the trough by cementing sameto the sides and ends of the trough A. Be-

tween the trough A and flannel B we arrange a sheet of perforated metalC or the like so that the flannel will be kept in position and yet thepowder will be allowed to percolate through the flannel B, the metalperforated sheet being shaped to the radius of the cylinder or travelingbed, so that the paper can be passed in perfect contact with the flannelover its entire surface. The dusting-trough is constructed in likemanner on the top part thereof.

The powder-applying troughs are fitted in a framework D, having arms Eresting in brackets F on the frame G of the machine, and such frames Dare connected to arms H of a rocking shaft I, this being connected by alink J to a crank-disk K, operated from some moving part of the machineto impart an oscillating motion to the troughs A and also dusting-box L,which rides on rollers M,

fitted in the frame of the machine.

Thetroughs and dusting-box may be divided into sections, so that morethan one colored powder can be applied and dusted at the same time, thedusting-trough being in register with the other troughs.

1n the machine shown, and which forms no part of this invention, eachsheet of paper to be bronzed is held by grippers on a cylinder andcarried round under the vibrating powder-troughs A to take up thepowder. The paper is then passed over the vibrating dusting-box toremove the surplus powder, and when the front edge of the paper reachesthe roller N the gripper releases it and paper passes away from thecylinder to a collecting apparatus, the cylinder making another completerevolution before taking up a fresh sheet. What we claim, and desire tosecure by Letters Patent, is v 1. In a bronzing-machine, the combinationwith oscillating or vibrating mechanism, of troughs for containing thebronzing material and cooperating with said mechanism, said troughshaving bottoms of chamois-leather, flannel, or the like through whichthe bronzing material is adapted to pass, the paper or other substanceto receive the bronzing material being fed against the saidtrough-bottoms. 2. In a bronzing-machine, the combination withoscillating or vibrating mechanism, of

means for removing'the surplus bronze from the material treated,consisting of a body having a top covering of flannel, chamoisleather,or the like, which has contact with the material treated.

8. In a bronzing-machine, the combination with oscillating or vibratingmechanism, of a trough having bottom coverings of chamois-leather,flannel, or the like, and against which the material to be bronzed ispassed, the bronzing-powder passing through the said trough-bottom, anda box having a top covour hands in presence of tWo subscribingWitnesses.
